Description

Technical Field

[0001] The utility model relates to the technical field of rainwater manhole covers, in particular to a rainwater manhole cover applicable to a sponge city. Background Technique

[0002] A sponge city means that the city can be like a sponge and has good "elasticity" in adapting to environmental changes and coping with natural disasters. When it rains, it absorbs, stores, seeps, and purifies water. When needed, the stored water is released and utilized; a rainwater well has holes on its side connected to a drainage pipe, and a water seepage pipe extending downward at the bottom, which can supplement rainwater underground and drain the excess rainwater through the drainage pipe, slowing down ground settlement and preventing the road surface from being flooded during heavy rain.

[0003] The utility model with the publication number CN214833317U discloses a rainwater well for a sponge city, which includes a rainwater well body and a manhole cover with drainage holes. A floating plate is arranged in the rainwater well body, a support rod is fixedly connected to the floating plate, the support rod is fixedly connected to the manhole cover, a placement groove is opened at one end of the opening of the rainwater well body, and one end of the manhole cover is slidably matched with the placement groove;

[0004] In the above technical solution, by setting the floating plate and the support rod, when encountering a heavy rainstorm, when the falling rainwater enters the rainwater well body through the drainage holes, as the water level rises, the floating plate moves upward, and then drives the support rod to move upward, pushing the manhole cover upward, thereby opening the manhole cover, increasing the gap between the manhole cover and the opening of the rainwater well body, and accelerating the speed of draining rainwater on the road surface into the rainwater well body; however, the conventional rainwater well manhole covers are all flush with the rainwater well, which cannot meet the large flow requirements of the sponge city. After the conventional rainwater manhole cover is installed, it is generally flush with the original ground, with a small flow rate and too fast a flow velocity, which easily leads to water accumulation in the seedlings around the rainwater well, causing the roots of the greening seedlings to rot after being soaked for a long time. At the same time, the surrounding greening leaves, twigs and other domestic garbage are easily piled up on the manhole cover, resulting in poor drainage and failing to play a role in initially intercepting and purifying the rainwater to isolate branches and leaves.
